Nimbostratusforce a next hop
Hi
I'm having a f5 which loadalance two links (outband connections) using ltm to a remote site.
I'm using one of the router to access to a backup link wich allow us to access to the remote site if the two links fails.
I'm using 3 transparent monitors to poll my gateways.
I would like to know, if the two links are down how the can tell to the router to use the backup by forcing him to use the backup link router as its next hop and not the principal router.
I hope my explanation is clear.
Thanks in advance for your help.

Hi Tarma,
I think I understand your scenario. You could use a pool for the gateways and use priority group activation to set the first two gateway pool members to a higher priority than the third one. The lower priority member would only be used if the first two are down.

tarma_58716Hello Aaron thanks for response.
But in my scenario i've one Router which is connected to two links.
So for the 3 links i've:
R1 <->R'1
R2 <-->R'2
R1 <-->R'3
where R1 et R2 are in my site and R'1, R'2 and R'3 are in the remote site.
I've added R1 twice as a member (in one i'm using a port dest so i can add again R1 as a member, the port will not be used cause in the VS i'm using all ports and i've disabled translate address and port)
i've 2 transparent monitors on R1, one pinging R'1 and the other is pinging R'3.
So if R'1 is down i've to use R'3 to access to the remote site, but how can i do for that? So the F5 should have to tell to R1 to pass throught R'3 and not R'1.

So the F5 should have to tell to R1 to pass throught R'3 and not R'1.just wondering when R'1 is down, doesn't R1 know it has to send traffic to R'3 instead of R'1? i thought R1 could have feature like cisco RTR/SLA.
